How many B-2's did we really make?

As most know the offical number of B-2 stealth bombers is at 21. However, having just finished the Reagan Diaries I came across an interesting mention dating back to 1986.

In one of his 1986 entires he discusses how to deal with the roll out of the 131's B-2 bomber. The 131's which would be capable of carrying nuclear cruise missiles would have violated SALT II. However Reagan decided that since the Societs were non compliant with the unpassed agreement, why should the US be.

It begs the question: How many did we make? Certainly the AF could not hide 131 of the aircraft givien the logistical tails it takes to maintain a fleet of that size unless it is buried in the heart of Nellis away from prying eyes.

THe question is was the huge production costs simply a smoke screen to cover the production of so many of the vehicles?

I suspect the high production costs have to do with the way the numbers fluctuated, and penalties for canceling airframes. From what I can remember of reading other sources, most contracts have a certain number of airframes that have to be bought to get the cost to a lower amount. If you cancel airframes and drop below that number, they add penalties to the contract amount that bring the cost up. The catch with the B-2s that we have now is that the cost would drop pretty big after the first 20. The first 20 would run them $2.2B/airframe, after that it would have dropped to $690M/airframe.

Initial procurement was for 132 airframes, with nuclear capability. After the Soviet Union started to crumble, it was changed to conventional capability, and dropped to 20+1. The one being a testbed that wasn't planned to be upgraded to operational standards.

we made enough to sell the plans to allies to create their own and with that money we were able to pay for some of our b-2's. only create whats neccesary, but you know us americans we love to waste.. prolly a few sitting at your neighborhood junkyard

isnt like a billion g's to build one of those?
